Troubleshooting
056
The slave DSP detects
that the leakage
current exceeds
inverter allowable
upper limit.
1. Check whether there is a ground fault of
the PV string.
2. If the fault occurs repeatedly, contact
SUNGROW.
059
Communication alarm
between master DSP
and slave DSP.
1. Wait 1 minute for inverter recovery.
2. If the fault persists, contact SUNGROW.
061
Alarm for no inverter
model setting.
Contact SUNGROW.
070
Fans are defective (-D
series only).
Stop the inverter and disconnect the AC &
DC cables. Check whether the fan duct has
been blocked. If not, replace fans.
084
Warning for reverse
cable connection of the
Energy Meter.
1. Check whether the power cable
connections are correct.
2. If “Existing Inverter” is set to “ON” via
LCD menu, check and ensure that its rated
power is correctly set.
3. For single-phase Energy Meter, check
whether the CT clamp of the 1-phase
sensor is correctly placed.
085
Mismatched software
version.
Please contact SUNGROW.
100
The AC output current
exceeds the upper
limit.
1. The inverter will resume if the output
current falls below the protection value.
2. If the fault persists, please contact
SUNGROW.
101
Grid over-frequency.
The grid frequency
exceeds the protective
value, which is higher
than the protective
value of error 008.
(stage II)
1. Check the grid frequency.
2. If the grid frequency exceeds the
permissible range of inverter protection
parameters, ask utility grid company for
solution.
3. If the grid frequency is within the
permissible range, contact SUNGROW.
102
Grid under-frequency.
The grid frequency is
below the protective
value, which is lower
than the protective
value of error 009.
(stage II)
105
SPI auto test fault (for
Italy only)
1. Restart the system and re-do the auto
